1 Claim.

' The present invention relates to the general class of coating withbrushing implements, and more specifically to an improved protectivejacket for paint brushes which while well adapted for use withhand-wielded paint brushes,-is especially designed as an attachment fora fountain type of brush that is supplied with liquid paint from apneumatic spray gun, or similar device, and manipulated as ahandimplement, for spreading or laying the paint upon a surface area. Inthis type of paint brush, the atomized liquid paint is usually forced orsprayed under airpressure through the head and bristle-body of .thebrush, and unless protective means are employed a portion of the paintis wasted as it is laterally expelled or dispersed from the body of thebrush before it reaches the flexible free end of the brush. The primarypurpose of the protective jacket of my invention is to confine theliquid paint from lateral dispersion, and to convey the paint supplydirectly to the free end of the brush. The jacket is also eiiective inprotecting and conserving the paint supply when used with either atypical paint brush,or a fountain type of sprayed brush, for overheadwork, to prevent waste usually caused by dropping of excess paint fromthe upended brush.

The quick detachable jacket may be manufactured in various sizes andshapes, of flexible material, at low cost of production, to produce acover for a portion of the bristle-body of the brush that is durable,and which may be readily cleansed and maintained in excellent conditionfor service.

The invention consists in certain novel features of construction andcombinations of parts as will hereinafter be described and moreparticularly set forth in the appended claim.

In the accompanying drawings I have illustrated a complete example of aphysical embodiment of my invention in which the parts are combined andarranged in accord with one mode I have devised for the practicalapplication of the principles of the invention. It will however beunderstood that changes and alterations are contemplated and may be madein these exemplifying drawings and structures, within the scope of myclaim, without departing from the principles of the invention.

Figure 1 is a view in elevation of a fountain type of paint brushequipped with the protective jacket of my invention; and Figure 2 is asimilar view with one section of the jacket turned outwardly.

Figure 3 is an edge View of the brush with one of the plackets open; and

Figure. 4 isa horizontal sectionalview at line 44 of Fig. 1, showing thetop of ,the jacketed brush. I

In this preferred form, of theinvention Ihave shown 'a'flat brush with abristle-body' 1,"; of

which the inner ends of the bristles 'arefgcbm pactly retained in ahollow head that includes two complementary sections 2 and 3 that areclamped together over and around the bristles by means of screw boltschaving their heads countersunk in the outer face of one of the sections, andfasten'ing nuts for the bolts arejcountersunk andshownat 5 inthefouter facefof the other head-section. 7 f 1 The enclosed bristlesare retained in such-manner as to permit forcible entry and passage ofliquid paint from a supply line or tube 6 that is connected in usualmanner with a spray gun, or other suitable source that supplies theliquid under pressure to the brush, and for connection of the tube withthe head 23, the latter is fashioned with a sectional nipple I that isexternally threaded and provided with a central bore or entry port 8that opens through the head into the bristle-body of the brush.

By means of a threaded coupling nut 9 that forms a socket for attachingthe nipple, the brush is attached at the end of the hose, and the fluidor liquid paint, by air under pressure, is forced through port 8 intothe upper end of the brush body, and dispersed through and from the freeflexible end of the brush in usual manner.

To prevent waste and dispersion, under pressure, of the liquid paintfrom the sides and opposite ends of the body adjoining the head, and toconvey the paint to the paint-spreading ends of the bristles of thebody, a closure, jacket, casing, or cover, is provided for a portion ofthe bristle-body, and the jacket or cover is equipped withquick-detachable fastening means for mounting the jacket over the headand upon a portion of the brush.

The jacket I0, which is fashioned of plastic, rubber, or other flexiblematerial, is provided with a continuous skirt or end portion l0, and twoopposed slits or plackets extend upwardly from the continuous skirt, toprovide openable or separable sections H and I2. The edges of theopposed plackets extend across the upper end of the jacket, and theadjoining edges of the plackets are cut out to form semi-circularnotches that provide an annular collar l3 that fits around the exteriorof the nipple I.

With the plackets in open position the upper open end of the jacket isslipped over the free flexible end of the brush with the skirt of thebrush fitting neatly over the bristles, and then the separated sectionsof the jacket are closed in over the head and around the nipple, and theplackets are securely closed by means of a pair of well known slidefasteners I 4 and [5, each having a slide key or handle-tab I6. Thelocking keysonslidinge handles are drawnrupwazdly along the.opposite'e'dges of the brush, and over and across the top of the head tothe opposite sides of the nipple I, and in this manner the jacketprovides a cover for a portion of the brush that does not interfere withfiowdi the-liquid paint, nor impede the wielding of thebrush and.

the laying on 01 the paint.

For cleansing the brush and 'its cover, when out of use, the two slidefasteners may-quickly be opened to permit removal of the jacket, anditrisslippedroff the free end of the brush and:separatedtherefrom'tar'thisjpurpose, to preserve the brush and the"jacket in proper condition for .use.

Having, thus. fully describedimy. invention, what Lclaimrasnew. and,desire: to secureflby Letters .Batent.is:.
